Couldn't the FBI compare handwriting in her notes to what was scrawled on the car to see if there are any similarities? This woman is still innocent until proven guilty.
If completely different, it would tend to point towards another person's spraycan, but if similar, she's in deeper doo-doo.

Here's another piece on this dunn deception. She's actually a very stupid person. The responding officers must have been suspicious the moment they saw the car, because the grafitti covered almost every "oppressed" group and were too neatly sprayed. The article I linked, suggests that Dunn has cost the community and the college quite a bit of money this week.
